Title: Some light antennae reading
Post by: Josh on January 31, 2019, 0021 UTC

The fine engineers at BBC have made available their findings in the realm of antennae (as well as other realms), peruse them here;

I find the papers on beverage and ferrite hf antennas to be particularly interesting;

Thanks Josh, the DIPOLE one is quite interesting too.

Thanks for these, some good theoretical info and real world factual stuff.

Ta!

Str.

I got sucked into the dipole white paper.  Great mix of theory and practical examples (both historical and modern), as str. mentioned.  I like how they didn't just stick to broadcasting but dive into land mobile radio and other uses in the discussion.

Very nice find indeed.

Almost unpossible to beat the efficiency of the lowly, forsaken, dipole. Glad you liked the white papers, what got me to the BBC site was a search for using small loops/short wires on hf, and this paper was right on topic;

Extending the range of a Discone antenna down to 3.6 MHz

This is nice for folks who don't have the ability or desire to deploy a more effective hf antenna than a discone.
